Competition - Bee friendly plants

Which plants are better for bees: native or non-native?

📖 Background

You work for the local government environment agency and have taken on a project about creating pollinator bee-friendly spaces. You can use both native and non-native plants to create these spaces and therefore need to ensure that you use the correct plants to optimize the environment for these bees.

The team has collected data on native and non-native plants and their effects on pollinator bees. Your task will be to analyze this data and provide recommendations on which plants create an optimized environment for pollinator bees.

💾 The Data

You have assembled information on the plants and bees research in a file called plants_and_bees.csv. Each row represents a sample that was taken from a patch of land where the plant species were being studied.

Column	Description
`sample_id`	The ID number of the sample taken.
`species_num`	The number of different bee species in the sample.
`date`	Date the sample was taken.
`season`	Season during sample collection ("early.season" or "late.season").
`site`	Name of collection site.
`native_or_non`	Whether the sample was from a native or non-native plant.
`sampling`	The sampling method.
`plant_species`	The name of the plant species the sample was taken from. None indicates the sample was taken from the air.
`time`	The time the sample was taken.
`bee_species`	The bee species in the sample.
`sex`	The gender of the bee species.
`specialized_on`	The plant genus the bee species preferred.
`parasitic`	Whether or not the bee is parasitic (0:no, 1:yes).
`nesting`	The bees nesting method.
`status`	The status of the bee species.
`nonnative_bee`	Whether the bee species is native or not (0:no, 1:yes).

💪 Challenge

Provide your agency with a report that covers the following:

Which plants are preferred by native vs non-native bee species?
A visualization of the distribution of bee and plant species across one of the samples.
Select the top three plant species you would recommend to the agency to support native bees.

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
%matplotlib inline
data = pd.read_csv("data/plants_and_bees.csv")
data

To begin data cleaning, I will farmiliarize my self with the data

# this will give the information about the dataset, the data tpye and nulls
data.info()

The information above shows that:

date is enter as string (object)
time is entered as int
the specification_on and status is almost empty
parasitic, nesting aand nonnative_bee has missing values

# this will show the statistics of the numeric data type present in the dataset
data.describe()

# checking foe nulls
data.isnull().sum()

For easier identification of fields, i will change two columns names

native_or_non to plant_type
nonnative_bee to bee_type

# change column names to suits analysis.

data.rename(columns={'native_or_non':'plant_type','nonnative_bee':'bee_type'}, inplace=True)

# Previewing the new columns
data.columns

Getting the unique values of some relevant columns

this is to help eliminate any mis-spelt value

data.sex.unique()

data.plant_species.unique()
